The tile that was affixed quickly fell, which is really a headache! But in addition to the raw material problems, some wrong practices in the construction will also cause the tiles to fall off.
Here are a few common questions
1. Can not add cement
Many construction workers add some cement to the tile adhesive when tiling. It feels that this can save the solidification time and is easy to stick firmly. It can be said to be both good and cheap. In fact, this practice is wrong, and even the consequences are very serious.
The ratio of the various ingredients in the product is very important. One or more points will affect the effect of the paving. Therefore, when using the tile adhesive, strictly follow the packing instructions, and do not add any additives at will.
2. Can not be thick
When the tile adhesive is on the wall, it is indispensable to use the concave shape of the toothed scraper. The thickness of about 3mm can be combed to make a beautiful stripe shape, which can be squeezed in the quick-paste method such as squeezing, squeezing, compacting and positioning. Excess air is released and the maximum area is tightly combined with the tiles.
However, in the course of use, workers often use tile adhesive as cement. They are thickly coated with one layer, so that they can be leveled and paved. In fact, these two steps cannot be saved, and the tile adhesive should not be thick. The expansion and contraction coefficients of the bonding layer and the tile and the wall are not matched, and the interface bonding strength is lowered, which brings great safety hazards.
3. Correct use of the scraper
No cement, no thick stickers, or bricks, it should be analyzed from the perspective of use.
The correct way is to use a tooth scraper to evenly form the tile adhesive into a toothed layout. Then, pick up the tile and press it down and press it up and down evenly.
4. Use of different tile adhesives
There are so many types of tiles, just how to use a kind of glue, so the type is not right, tile glue is powerless.
The matching between materials mainly shows the following aspects:
★ Tile adhesive and tile specifications and materials match, low water absorption tiles use high quality tile adhesive.
★ The performance of the tile adhesive is matched with the application base layer, and the shrinkage deformation is larger. The base layer is made of flexible tile adhesive.
★ Tile adhesive should be matched with the application environment. In environments with high humidity, water resistance should be good.
Product introduction
Tongmei Tu tile adhesive is a new material for modern decoration. It replaces the traditional cement yellow sand. The adhesive strength is several times that of cement mortar. It can effectively paste large tile stone and avoid the risk of brick falling. Good flexibility to prevent the production of empty drums.
Features
▲ high shear strength and bond strength
▲ strong applicability and good stability
▲ superior waterproof performance and operating performance
▲ high paving efficiency
▲No pollution to all kinds of wall decoration materials, easy cleaning of tools and bricks
Scope of application
★ Suitable for the application of tiles with dimensions less than 600x300mm on indoor and outdoor concrete or cement mortar wall and vertical surface
★ Anti-seepage layer for building exterior walls, swimming pools, bathrooms, etc.
★ Suitable for all kinds of horizontal floor tiles
Precautions
★ The water used for mixing the binder must use clean water (eg clean tap water). It is strictly forbidden to use water containing impurities or contaminated water.
★ In the process of mixing the binder with water, if there is too much water to be mixed, the water should not be drained. It can be adjusted to the required level by adding the binder dry powder; the dried slurry is prohibited from adding water and then used.
★ Do not add other materials and additives during the process of preparing the adhesive.
★ After adjusting the slurry, it is better to use it within 2 hours.
★ Do not immerse the adhesive in water
★ Due to different weather conditions, wall environment and other factors, the water-cement ratio should be adjusted. If necessary, trial work should be carried out.
